A zamanin ci gaban fasaha, tsarin kewayawa ya fito a matsayin ginshiƙai, yana haifar da ci gaba da yawa, musamman ma a fagage masu mahimmanci.Tafiya daga kewayawa na sama zuwa ga nagartaccen Tsarin Kewayawa Inertial Navigation Systems (INS) yana kwatanta ƙoƙarin ɗan adam na rashin jajircewa don bincike da nuna daidaito.Wannan bincike ya zurfafa cikin ingantattun makanikai na INS, yana binciken fasahar yankan-baki na Fiber Optic Gyroscopes (FOGs) da kuma muhimmiyar rawar Polarization a Kula da madaukai na Fiber.
Sashe na 1: Tsare Tsare-tsaren Kewayawa Inertial (INS):
Tsarukan Kewayawa Inertial (INS) sun yi fice a matsayin mataimakan kewayawa mai cin gashin kai, daidai gwargwado suna ƙididdige matsayin abin hawa, daidaitawa, da sauri, mai zaman kansa ba tare da alamun waje ba.Waɗannan tsarin sun daidaita motsi da na'urori masu juyayi, suna haɗawa ba tare da matsala ba tare da ƙirar ƙididdigewa don saurin farko, matsayi, da daidaitawa.
INS na archetypal ya ƙunshi abubuwa masu mahimmanci guda uku:
· Accelerometers: Waɗannan abubuwa masu mahimmanci suna yin rijistar hanzarin linzamin abin hawa, suna fassara motsi zuwa bayanan da za a iya aunawa.
· Gyroscopes: Haɗe-haɗe don tantance saurin kusurwa, waɗannan abubuwan suna da mahimmanci ga daidaita tsarin.
Module Kwamfuta: Cibiyar jijiya ta INS, sarrafa bayanai masu yawa don samar da ƙididdigar matsayi na ainihi.
Kariyar INS ga rushewar waje ya sa ya zama dole a sassan tsaro.Duk da haka, yana kokawa da 'drift' - lalacewar daidaito a hankali, yana buƙatar ingantattun mafita kamar haɗakar firikwensin don rage kuskure (Chatfield, 1997).
Sashe na 2. Dynamics na Aiki na Fiber Optic Gyroscope:
Fiber Optic Gyroscopes (FOGs) yana ba da sanarwar zamani mai canzawa a cikin jujjuyawar ji, yana ba da damar tsoma bakin haske.Tare da daidaito a ainihin sa, FOGs suna da mahimmanci don daidaitawar motocin sararin samaniya da kewayawa.
FOGs suna aiki akan tasirin Sagnac, inda haske, kewayawa cikin kwatance a cikin madaurin fiber mai jujjuya, yana nuna canjin lokaci wanda ke daidaitawa tare da sauye-sauyen juyi.Wannan ƙayyadaddun tsarin yana fassara zuwa madaidaicin ma'aunin saurin kusurwa.
Abubuwan da ake buƙata sun haɗa da:
Tushen Haske: Wurin farawa, yawanci Laser, wanda ke fara tafiyar haske mai daidaituwa.
· Fiber Coil: Ƙwallon gani na gani, yana tsawaita yanayin haske, ta haka yana haɓaka tasirin Sagnac.
· Photodetector: Wannan bangaren yana gano tsangwama na tsangwama na haske.
Sashe na 3: Muhimmancin Kula da madaukai na Fiber:
Kula da Polarization (PM) madaukai na Fiber, mahimmanci ga FOGs, tabbatar da daidaitaccen yanayin yanayin haske, maɓalli mai ƙayyadaddun ƙayyadaddun tsangwama.Waɗannan ƙwararrun zaruruwa, yana yaƙi da tarwatsa yanayin polarization, ƙarfafa azancin FOG da amincin bayanai (Kersey, 1996).
Zaɓin filayen PM, waɗanda aka faɗa ta hanyar fitar da aiki, halayen jiki, da jituwa na tsari, suna tasiri ga ma'aunin aikin da ya wuce kima.
Sashe na 4: Aikace-aikace da Hujjojin Hujja:
FOGs da INS suna samun karɓuwa a cikin aikace-aikace daban-daban, tun daga ƙirƙira jiragen sama marasa matuƙa zuwa tabbatar da kwanciyar hankali na cinematic tsakanin rashin hasashen muhalli.Shaida ga amincin su shine tura su a cikin Mars Rovers na NASA, suna sauƙaƙe kewayawa na waje mara aminci (Maimone, Cheng, da Matthies, 2007).
Hanyoyi na kasuwa suna yin hasashen haɓakar haɓaka ga waɗannan fasahohin, tare da ɓangarorin bincike da nufin ƙarfafa juriyar tsarin, matrix daidai, da yanayin daidaitawa (Kasuwanci, 2020).
